As ever the bundle comes in tiers, so you pay a minimum of £1 for the first set of games, pay more than the average for the next set, and so on. This time there is a little twist though, as the first tier offers up Insurgency, plus 3 other copies to share with your friends. If you share all 3 copies you bag yourself an extra game - Full Mojo Rampage.

Here's the bundle trailer.

Right, so here's the list of games on offer, and what you need to donate to get them:

Pay a minimum of $1 to receive:

Tesla Effect: A Tex Murphy Adventure

Always Sometimes Monsters

Insurgency (share 3 the extra 3 copies to receive Full Mojo Rampage)

Pay more than the average (currently $6) to receive the above and:

GRID 2

Blackguards

Euro Truck Simulator 2

More games to be added soon

Pay $12 or more to receive the above and:

Saints Row IV

Some of the games' soundtracks are also included.

There's still just over a day left on the Racing bundle that's on offer too, so check that out if full-on racing is more your style.
